I have set up the following configuration to monitor input and output errors on a Cisco router.

WorkDir: /var/opt/OV/mrtg/htm

Target[ferrors]: at
MaxBytes[ferrors]: 1000
Title[ferrors]: Line Errors on Fishers T-1
PageTop[ferrors]: <H1><CENTER>Input and Output Line Errors <BR>on AH to Fishers T-1<BR></CENTER></H1>
WithPeak[ferrors]: mwy

MaxBytes[fdropss]: 1000
Title[fdropss]: Packet Drops on Fishers T-1

MRTG collects the data from the router but it only updates the first line of the log file.  Each subsequent sample replaces the first line only.  The deltas are not being calculated for the difference between the 5 minutes samples.  Any help or suggestions would be appreciated.
